Description

Technical Field

[0001] This utility model relates to the field of valve positioner technology, specifically to an adjustable mounting bracket for valve positioners. Background Technology

[0002] A valve positioner is an automatic control device used to control the opening degree of a valve. It receives signals from the control system (such as electrical signals, pneumatic signals, etc.) and then converts these signals into corresponding forces to adjust the valve opening. The installation structure of a valve positioner is a support structure used to fix the positioner body to the valve or actuator. The design of the installation structure needs to consider factors such as the type of positioner, the type and size of the valve, etc. Because the installation structure of valve positioners in related technologies cannot be adjusted in height, the distance between the positioner and the valve is unsuitable, which in turn affects the angle of the linkage, leading to inaccurate force transmission and a mismatch between the valve opening and the control signal. Furthermore, the inability to adjust the height may result in insufficient space between the positioner and the valve for installation, requiring additional supports or other auxiliary structures, increasing installation difficulty and cost. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an adjustable mounting bracket for valve positioners, which can effectively solve the problems in the prior art.

[0004] The technical solution adopted by this utility model is: an adjustable mounting bracket for a valve positioner, including a valve body, a valve positioner body, and an electric actuator located on top of the valve body. A connecting rod is fixedly installed between the valve body and the electric actuator. A connecting plate is provided on the side of the connecting rod away from the valve positioner body. A connecting groove is opened at the end of the connecting plate near the connecting rod. A connecting seat is provided on the side of the connecting rod near the valve positioner body. A slider is fixedly installed at the end of the connecting seat near the connecting plate. A support plate is fixedly installed at the bottom of the end of the connecting seat away from the connecting plate. A positioning column is fixedly installed at the end of the support plate near the valve positioner body. A reinforcing block is fixedly installed at the end of the support plate near the connecting rod. A positioning groove is opened at the end of the valve positioner body near the support plate.

[0005] Preferably, a handwheel is provided on the side of the connecting plate away from the connecting rod, and a screw threadedly connected to the connecting plate is fixedly installed at the end of the handwheel near the connecting plate. An extrusion block is fixedly installed at the end of the screw away from the handwheel. The extrusion block has a circular cross-section and its radius is larger than that of the screw.

[0006] Through the above technical solution, by setting a handwheel, screw, and extrusion block, the operator can manually turn the handwheel to drive the screw to rotate, thereby causing the extrusion block to exert an extrusion force on the connecting rod. This structure can easily realize the tightness adjustment between the connecting plate and the connecting rod, so that the operator can fix or adjust the position of the connecting plate according to actual needs. By setting the cross-section of the extrusion block to be "circular" and the radius of the extrusion block being larger than the radius of the screw, the contact area of ​​the connecting rod can be effectively increased, thereby strengthening the connection strength between the connecting plate and the connecting rod.

[0007] Preferably, the slider is adapted to the connecting groove, the slider and the connecting groove are slidably connected, and the cross-section of the slider has a "T" shaped structure.

[0008] With the above technical solution, the slider and the connecting groove are designed to slide together. When installing the connecting seat, the slider can be aligned with the connecting groove and inserted to achieve the positioning and installation of the connecting seat, thereby improving the installation efficiency. By setting the cross-section of the slider to be a "T" shape, the structural stability and connection strength can be effectively enhanced. Furthermore, the longitudinal embedding of the "T" shape into the connecting groove can prevent the slider from accidentally falling off during the extrusion process.

[0009] Preferably, the positioning groove and the positioning post are plugged in. The positioning post has a through-hole at the center of one end near the valve positioner body. The support plate has a locking bolt on the side away from the valve positioner body. The locking bolt passes through the positioning post and extends into the interior of the valve positioner body.

[0010] The above technical solution, through the design of the positioning groove and the positioning column for plug-in installation, enables the initial positioning and installation of the valve positioner body and the support plate. Then, by tightening the bolt through the positioning column and extending into the interior of the valve positioner body, the valve positioner body can be quickly fixed. It also facilitates the quick disassembly of the valve positioner body, making it convenient for later maintenance and replacement.

[0011] Preferably, the cross-section of the reinforcing block is triangular, and three identical sets of reinforcing blocks are provided, with the three sets of reinforcing blocks located at the bottom of the support plate and distributed at equal intervals.

[0012] The above technical solution uses a triangular cross-section for the reinforcing blocks. This triangular structure provides good stability and load-bearing capacity. Furthermore, the presence of three identical sets of reinforcing blocks at equal intervals greatly enhances the support strength of the support plate.

[0013] Preferably, the connecting seat and the connecting rod are slidably connected, and the cavity formed by the connecting seat and the connecting plate is larger than the cross-section of the connecting rod.

[0014] Through the above technical solution, the design of the connecting seat and the connecting rod as a sliding connection allows the connecting seat to move up and down along the connecting rod. The cavity formed by the connecting seat and the connecting plate is larger than the cross-section of the connecting rod, providing sufficient space for the sliding of the connecting seat and the connecting plate on the connecting rod, avoiding movement obstruction due to insufficient space. The connecting seat and the connecting plate are quickly fixed to the connecting rod by cooperating with the handwheel, screw and pressing block.

[0015] Compared with the prior art, this utility model provides an adjustable mounting bracket for a valve positioner, which has the following advantages:

[0016] 1. This adjustable mounting bracket for valve positioners places the connecting plate and connecting seat at both ends of the connecting rod. The sliding connection between the slider and the connecting groove allows for quick installation of the connecting plate and connecting seat. The "T"-shaped cross-section of the slider effectively enhances structural stability and connection strength. The sliding connection between the connecting seat and the connecting rod allows the connecting seat to move up and down along the connecting rod. The cavity formed by the connecting plate is larger than the cross-section of the connecting rod, providing sufficient space for the sliding of the connecting plate and connecting seat on the connecting rod, avoiding obstruction of movement due to insufficient space. Subsequently, with the help of a handwheel, screw, and pressing block, the operator can manually rotate the handwheel to drive the screw to rotate, thereby causing the pressing block to exert a pressing force on the connecting rod. This structure allows for convenient adjustment of the tightness between the connecting plate and the connecting rod, making it easy for operators to fix and adjust the position of the connecting plate and connecting seat according to actual needs.

[0017] 2. This adjustable mounting bracket for valve positioners features a design where the positioning groove and positioning column are plugged in for initial positioning of the valve positioner body and the support plate. Subsequently, locking bolts are used to pass through the positioning column and extend into the interior of the valve positioner body, enabling quick fixation of the valve positioner body. This also facilitates quick disassembly of the valve positioner body, making it easier for later maintenance and replacement. By fixing three sets of reinforcing blocks with a "triangular" cross-section at equal intervals at the bottom of the support plate, the support strength of the support plate is greatly enhanced.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: As Figure 1-8 As shown, this utility model provides an adjustable mounting bracket for a valve positioner, including a valve body 1, a valve positioner body 4, and an electric actuator 2 located on top of the valve body 1. A connecting rod 3 is fixedly installed between the valve body 1 and the electric actuator 2. A connecting plate 5 is provided on the side of the connecting rod 3 away from the valve positioner body 4. A connecting groove 9 is provided at the end of the connecting plate 5 near the connecting rod 3. A connecting seat 10 is provided on the side of the connecting rod 3 near the valve positioner body 4. A slider 11 is fixedly installed at the end of the connecting seat 10 near the connecting plate 5. A support plate 12 is fixedly installed at the bottom of the end of the connecting seat 10 away from the connecting plate 5. A positioning column 13 is fixedly installed at the end of the support plate 12 near the valve positioner body 4. A reinforcing block 16 is fixedly installed at the end of the support plate 12 near the connecting rod 3. A positioning groove 17 is provided at the end of the valve positioner body 4 near the support plate 12.

[0029] Specifically, a handwheel 6 is provided on the side of the connecting plate 5 away from the connecting rod 3. A screw 7, threadedly connected to the connecting plate 5, is fixedly installed at the end of the handwheel 6 near the connecting plate 5. A pressing block 8 is fixedly installed at the end of the screw 7 away from the handwheel 6. The pressing block 8 has a circular cross-section, and its radius is larger than that of the screw 7. The advantage is that by setting up the handwheel 6, screw 7, and pressing block 8, the operator can manually rotate the handwheel 6 to rotate the screw 7, thereby causing the pressing block 8 to exert a pressing force on the connecting rod 3. This structure allows for convenient adjustment of the tightness between the connecting plate 5 and the connecting rod 3, making it easy for the operator to fix or adjust the position of the connecting plate 5 according to actual needs. Furthermore, by setting the pressing block 8 to have a circular cross-section and a radius larger than that of the screw 7, the contact area of ​​the connecting rod 3 is effectively increased, thereby strengthening the connection strength between the connecting plate 5 and the connecting rod 3.

[0030] Specifically, the slider 11 is adapted to the connecting groove 9, and the slider 11 and the connecting groove 9 are slidably connected. The cross-section of the slider 11 is T-shaped. The advantage is that, through the design of the slider 11 and the connecting groove 9 being slidably connected, when installing the connecting seat 10, the slider 11 can be aligned with the connecting groove 9 and inserted, thereby achieving the positioning and installation of the connecting seat 10 and improving installation efficiency. By setting the cross-section of the slider 11 to a T-shape, the structural stability and connection strength can be effectively enhanced. Furthermore, the longitudinal embedding of the T-shape into the connecting groove 9 can prevent the slider 11 from accidentally falling off during the extrusion process.

[0031] Specifically, the positioning groove 17 and the positioning post 13 are installed by insertion. A through-hole screw hole 14 is centrally located at the end of the positioning post 13 closest to the valve positioner body 4. A locking bolt 15 is provided on the side of the support plate 12 away from the valve positioner body 4. The locking bolt 15 passes through the positioning post 13 and extends into the interior of the valve positioner body 4. The advantage is that the insertion-installation design of the positioning groove 17 and the positioning post 13 allows for initial positioning and installation of the valve positioner body 4 and the support plate 12. Subsequently, the locking bolt 15, passing through the positioning post 13 and extending into the interior of the valve positioner body 4, enables rapid fixation of the valve positioner body 4. It also facilitates quick disassembly of the valve positioner body 4, making subsequent maintenance and replacement easier.

[0032] Example 2: Figure 2-8 As shown, this is an improvement on the previous embodiment.

[0033] Specifically, the reinforcing block 16 has a triangular cross-section, and three identical sets of reinforcing blocks 16 are arranged at equal intervals at the bottom of the support plate 12. The advantage is that by setting the reinforcing block 16 to a triangular cross-section, the triangular structure provides good stability and load-bearing capacity. Furthermore, the equal-interval arrangement of the three identical sets of reinforcing blocks 16 significantly enhances the support strength of the support plate 12.

[0034] Specifically, the connecting seat 10 and the connecting rod 3 are slidably connected, and the cavity formed by the connecting seat 10 and the connecting plate 5 is larger than the cross-section of the connecting rod 3. The advantage is that the slidable connection between the connecting seat 10 and the connecting rod 3 allows the connecting seat 10 to move up and down along the connecting rod 3. Furthermore, the larger-than-normal cavity provides sufficient space for the sliding of the connecting seat 10 and the connecting plate 5 on the connecting rod 3, preventing movement obstruction due to insufficient space. The connecting seat 10 and the connecting plate 5 are quickly fixed to the connecting rod 3 by using the handwheel 6, screw 7, and pressing block 8.

[0035] Working Principle: In use, first install the connecting plate 5 and the connecting seat 10 at both ends of the connecting rod 3. The slider 11 is slidably connected to the connecting groove 9. Aligning the slider 11 with the connecting groove 9 and inserting it allows for the positioning and installation of the connecting seat 10, improving installation efficiency. The "T"-shaped cross-section of the slider 11 effectively enhances structural stability and connection strength. Furthermore, the longitudinal embedding of the "T"-shaped structure into the connecting groove 9 prevents the slider 11 from accidentally falling off during the extrusion process. The slidable connection between the connecting seat 10 and the connecting rod 3 allows the connecting seat 10 to move up and down along the connecting rod 3. The cavity formed by the connecting seat 10 and the connecting plate 5 is larger than the cross-section of the connecting rod 3, providing sufficient space for the sliding of the connecting seat 10 and the connecting plate 5 on the connecting rod 3, avoiding obstruction of movement due to insufficient space. Combined with the handwheel 6, screw 7, and extrusion block 8, the operator can manually rotate the handwheel 6 to rotate the screw 7, thereby allowing the extrusion block 8 to move. The connecting rod 3 is subjected to a compressive force. This structure allows for easy adjustment of the tightness between the connecting plate 5 and the connecting rod 3, making it convenient for operators to fix or adjust the position of the connecting plate 5 according to actual needs. By setting the cross-section of the compression block 8 to be circular, and the radius of the compression block 8 being larger than the radius of the screw 7, the contact area of ​​the connecting rod 3 is effectively increased, thereby strengthening the connection strength between the connecting plate 5 and the connecting rod 3. Subsequently, the valve positioner body 4 and the support plate 12 are initially positioned and installed by the insertion installation design of the positioning groove 17 and the positioning column 13. Then, the valve positioner body 4 is quickly fixed by the locking bolt 15 penetrating the positioning column 13 and extending into the interior of the valve positioner body 4. This also facilitates the quick disassembly of the valve positioner body 4, making it convenient for later maintenance and replacement. By fixing three sets of reinforcing blocks 16 with a triangular cross-section at equal intervals at the bottom of the support plate 12, the support strength of the support plate 12 is greatly enhanced.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
